A heating, ventilation and air conditioning system with a direct drive blower is when the blower motor is connected directly to the fan. As the motor operates and turns the shaft, the fan moves accordingly.
Direct drive blowers are used in air conditioners, roof ventilators, exhaust fans, furnaces, and other applications that require moving air in or out of a system.
For changing a direct drive blower you’ll need to know the motor diameter in inches, voltage, horsepower (HP), RPM, number of speeds available, direction of rotation, mounting method, and the size of the run capacitator required. Note that some older units have the mounting brackets built into the motor, if this is the case, you will need to purchase the exact replacement or a motor and an adapter kit.
We have a variety of direct drive blowers available from 50CFM up to 1638CFM, single and multispeed, and single phase. Contact us for more information.
